[Released] BFS WP8 Goodies Plugin

I don't get the purchase display page when I click the button for the consumable, just comes up with the error straight away.

I'll try it without the numbers to see how it goes.

Cheers,

TerraCo

 

Hi Kyle,

Just one question is it mandatory to have VS Express edition or we can do build the project with any other VS edition as well?

-Amol

 

No luck.

Created a new item called "fuelcan". Submitted the beta app, downloaded the app once it was approved and went to purchase the new item. Got the blank Confirm page. Restarted app and purchased the item successfully. Went to purchase the item again and got the same error as above where it crashes at WP8Goodies.IAP.<RequestPurchaseAsync>d_3.Move.Next()

Uninstalled, restarted phone, reinstalled. Still get the same error.

 

Hi Amol,

VS Express edition is not required - it is just the free version available, but Unity also supports Visual Studios Professional I believe.

-Kyle

 

Hi TerraCo,

Thanks a bunch for your feedback - I have some theories as to what might cause it based on what you have described. Will give them a shot see if I can resolve this issue. Hopefully will have something to try out tomorrow, will keep you all posted here!

-Kyle

 

Sounds great to me, I eagerly anticipate your update. Will this address the blank Confirm page issue as well?
Feature request: Are there plans to add pubCenter to this plugin?

Also, I can confirm that Unity supports the Pro versions of Visual Studio. I have used 2012 Pro and am now using 2013 Beta Pro with zero issues.

 

Hi TerraCo, Amol,

I have been able to reproduce the issue of the blank confirm page. It will happen if you call the function

Code (csharp):

1.  
2. WP8Goodies.IAP.RequestPurchase("");
3.  

twice in rapid succession. This could happen because e.g. the Button Trigger code you are using is accidentally firing off twice, and so the IAP function is called twice. Put in some Debug Logs to see if it is being called twice, and if it is make sure that it will only get called once.

TerraCo,

As for your "fuelcan" test - it is possible that you have an out-dated version of the plugin, or maybe a related issue to do with the purchase call being fired twice. Make sure you have the latest version from the Asset Store, and not calling the purchase function twice. If it is still happening for you - is this item a durable or consumable?

Hope this helps you guys, let me know if you still have any issues.

P.s. a new update will be going out soon for the IAP product details so you can retrieve the price / description from within the app - will be live on the asset store in the next week or two (just have some final testing here, then submitting to the store for approval )

Cheers,

-Kyle

 

Hi Kyle,

Thanks for this - have adjusted and will be testing as soon as beta is approved, will let you know the results.

Update will be welcomed! Any thoughts on ingame-ads?

 

Hi Kyle,

I tested this out and did find an issue with my buttons firing too many times. This has been resolved and they now fire a maximum of once every 5 seconds. There seems to be an issue with the IAP functions in that they seem to send off 3 requests and return 3 results every time. It also returns 3 errors each time it fails.

My coin purchase works, but gives the player 3 times the amount that they purchase. The fuelcan purchase still returns the error stating the "Operation is not valid due to the state of the object" as shown in my screenshots from earlier

EDIT: The triplication thing is on my end. When I click ANY button, they all fire a purchase. I'll sort that out. Still getting the error with some purchases though. Is there any updated IAP script you can send through or do I have to wait for the update? Just trying to get this game ready for the Unity/Windows comp

 

Hi TerraCo,

For the first issue, it would probably be that you are assigning a function to the OnIAPPurchaseSucceeded event multiple times, and/or adding it when you go to the IAP screen, but not removing it when you go away (so each time you return to the IAP screen it will call it one additional time). Double check to make sure every time you add a listener to the event, you also remove it when it is finished.

As for the fuelcan - is that a Durable IAP item?

-Kyle

 

Hi Kyle,

I got the triple call issue sorted, scripting issue. The fuelcan (not working) is a consumable item, just like the hundredBucks item (which now works). I have a Durable item which works as well.

The fuelcan button doesn't even go and check the store. As soon as it is clicked it throws up the error.

Cheers,
TerraCo

 

Hi Kyle,

I have also checked for the button triggered .. It is calling once only.
Still giving the same error.

Regards,
-Amol

 

Hi Amol,

Hmm... if you are 100% certain that it is only being called once and still causes the issue then it could be something else entirely.

What I would suggest is something like the following just as a test:

Code (csharp):

1.  
2. void OnBuyButtonClicked()
3. {
4.     PurchaseIAPItem("your.iap.here");
5. }
6.  
7. void PurchaseIAPItem(string a_ProductID)
8. {
9.     StartCoroutine(PurchaseIAPItemDelayed(a_ProductID));
10. }
11.  
12. IEnumerator PurchaseIAPItemDelayed(string a_ProductID)
13. {
14.     yield return new WaitForSeconds(UnityEngine.Random.Range(1f, 2f));
15.    
16.     WP8Goodies.IAP.RequestPurchase(a_ProductID);
17. }
18.  

This will ensure two things:

1. It will (most of the time) ensure it is not called twice in a row (due to the random delay).
2. It will ensure that any other WP8 dialogues that are being used will be finished up by the time the IAP purchase will be processed.

If you can run this test and see if it works for you then, that will limit what the possibilities are for your error.

Cheers,

-Kyle

 

Hi TerraCo,

Not sure whats happening with fuelcan then - is the setup exactly the same as for the hundredbucks? Try swapping the two and see if the reverse happens (hundredbucks doesnt work, but fuelcan does).

If when you swap them, fuelcan still doesnt work, it looks like it is a problem with the IAP product ID in the beta store - try deleting / recreating it.

If when you swap them, hundredbucks stops working, then there is a problem with how you are calling the function to buy the fuelcan and you should check it to make sure it works in the same way.

Let me know how this goes for you,

-Kyle

 

OK, Will try the same will get back to you.

Regards,
-Amol

 

Thanks for those suggestions Kyle.

I have since changed the fuelcan to be an in game item, not purchased through the store. So I should be good from here!

Thanks for the great support!

Cheers,

TerraCo

 

Hello,
I bought your plugin. I have not tried to implement it yet, it's just a question about process. For iOS Storekit for example you have to request the products first, this is very useful because i can retrieve the price from the store and this can change depending on location and display it to the user.

I don't see a request product method just RequestPurchase. Please help

 

i am getting this error

failed to purchase [in app identifier] with error[An unknown error]. If you are running directly from a unity build without any link to Windows Store this can happen.

 

Hi DarJam,

This functionality should be coming in an update soon to the asset store - keep an eye out for it!

-Kyle

 

Hi,

You will get this error if you build and run the game directly from the unity editor. You cannot test IAP for Windows Phone without linking it to the Windows Phone Store - you can do this by logging in to the Windows Phone Developer Centre and setting up a new Beta app (which will remain private), then following the instructions there to upload your app and test it in the beta store.

Let me know if you have any problems,

-Kyle

 

all m doing is generating the BFS Goodies Plugin code from unity3d after changing the in-app purchase id to my beta testing ID, and running that on WP8 device

Do i need to do something more ??

 

heres a screenshot of the status

 

Thanks Kyle for the reply.
I don't know if MS do currency conversion on IAP, if they don't then it's possible to get away with it by omitting the currency symbol. If MS do currency conversion then its a big miss for me.

 

Hi DarJam,

My understanding is that it provides a localised string value for the price, so you can just display that string straight in your GUI. But if that doesn't match your needs, then you might be able to parse the string to get some numerical value from it.

-Kyle

 

Hi,

It looks like it is all set up correctly - but are you running the BETA version of the app, or running straight from unity / visual studio?

Simply having an app installed that is the same name as a beta app will not work. What you should do is delete your app off your phone, then go to the email you received from the windows store in regards to your Beta app submission. This will give you a link to the store where you can download your app in its BETA form. You can run this downloaded build and test your IAP.

Let me know if you still have any issues.

-Kyle

 

didnt got any email from microsoft about the beta build..

What i did was that i installed the game from visual studio on my phone and uploaded the same xpa to the windows store as beta build.

Am i doing it wrong ?

 

Hi,

Yeah - that won't work. When you uploaded the beta build, you would have been asked to enter email addresses as recipients for the build. All of the email addresses entered there would have received an email telling them how to download the beta version of the app. Double check to make sure your email is in there, and entered correctly. Note that it might take a few hours for the email to go out.

-Kyle

 

The update has just been approved and is now up in the store!

This update contains features for loading details about your IAP items, such as their price, so that it can be displayed in-game.

Hope it helps a few of you requesting this feature!

-Kyle

 

Kyle,
first of all thanx for the plugin! Most things work great for me!
My most important one seems to be acting weird though, IAPs. I am loading the items correctly from the store to my UI(the game is in beta and the IAPs are also in beta - the game was installed directly from the beta store) but when I request a purchase the result is unpredictable. It can work at one time, taking me to the "Confirm Purchase" Microsoft UI and then back to the game giving me the item and if I try to buy the same IAP, it will just crash the game. Most of the times though, it will crash while trying to buy any item before or after the MS IAP "confirm" UI. It's just an unstable mess

Here is the code I am using:

For getting the products' info: (this works)

Code (csharp):

1.  
2. WP8Goodies.IAP.OnRetrieveAllProductListingsSucceeded+=addItems;
3. WP8Goodies.IAP.RequestAllProductListings();
4.  

For actually buying the item:

Code (csharp):

1.  
2. WP8Goodies.IAP.OnIAPPurchaseSucceeded+=giveItems;
3. WP8Goodies.IAP.OnIAPPurchaseFailed+=error;
4. WP8Goodies.IAP.RequestPurchase(productID);
5.  

So I am not doing anything fancy, just normal stuff. And I know it works, because sometimes, well, it works Even trying to buy the same item twice (waiting a few seconds in between after the first successful buy) may crash the app.
All items I mention are consumables.

Any ideas? Anything I can do to help debug this?

 

Hi Kairos,

I have seen this sort of behaviour pop up for various things - it may be because you are calling the RequestPurchase function multiple times in a single frame. By the looks of the code, it would not happen, but it is possible that the click event you are detecting is firing off the purchase function multiple times. If you are using NGUI for Windows Phone, there have been some old bugs which could trigger the same event multiple times.

I would suggest trying the sample GUI provided, replace the iap details with your actual IAP details, and then upload that as a beta to the store. If the sample GUI is working fine, then the problem is likely to be in how you're GUI is handling the function call.

Let me know how it goes for you.

-Kyle

 

Hi,

Can you add functionality to get receipts?
I would like to get receipts of all purchased items and as result from purchase.

 

What social networks support for winphone?

 

Hi there,

We have implemented the WP8 goodies bundle and managed to get successful purchases through IAP (we are only using consumables). However, we have just had a non-compliant issue come through:

The application does not award Consumable IAP item(s) properly when the purchase cycle is interrupted.
Steps to reproduce:
1. Launch the application.
2. Purchase 15 stars.
3. After the purchase completes but prior to the purchase flow returning to the application, press the device start button.
4. Re-launch the application.
5. Note that the stars have not been awarded.
6. Attempt to repurchase 15 stars.
7. Note that the stars cannot be purchased because the previous purchase has not been awarded.

In addition to this we were also sent through a link to:
http://blogs.windows.com/windows_ph...-to-test-common-in-app-failure-scenarios.aspx where they reference DoFullfillment() from the In-App Purchase API documentation.


On our side, at the start we call the WP8Goodies.IAP.RequestAllProductListings() after subscribing to all the events
and after that we call WP8Goodies.IAP.RequestPurchase(). All works fine but we don't know how to deal with the situation where the plugin has failed deal with a purchase and not redeemed a consumable.

Have we missed a step somewhere or is this possibly a bug in the plug-in?

This currently applies to a live product so we would love to resolve this as soon as possible.

Thanks for your time, your help is appreciated,

Andrew M.

 

Hi Andrew,

Thanks for your bug report - it seems that by quitting before the purchase has been fully completed as described in the steps above, the plugin doesn't get a chance to fulfill the purchase properly, and doesn't check for purchases in progress. I will work on adding this functionality in ASAP with a new version.

-Kyle

 

Brilliant stuff Batman!

Please let us know when that is ready to rock

A.

 

Hi,
I've been using your plugin a lot lately, especially in my game Pastry Push and now Hues.

I want to know if there is a way to check if a user has already purchased some items (Inapp purchase) so that I can give the user the benefit, after he switch device.

In my case actually, one of the In app was not set up properly, so people didn't recieve the benefits from the purchase but were charged for it. So I need to check if any users have purchased it previously, and give them the required benefits.

Thanks,
Waiting for your reply

 

Hi PuneetK,

What you are after is the function WP8Goodies.IAP.RequestAllProductListings() function. When you call that, it will fire off an event which you can listen to with WP8Goodies.IAP.OnRetrieveAllProductListingsSucceeded (or WP8Goodies.IAP.OnRetrieveAllProductListingsFailed if there is an error). This will pass a list of ProductListing objects which you can look at to see if they are active or not for the current user.

Hope this helps.

-Kyle

 

So, you are saying that RequestAllProductListings() will give me a list of products for the current user?

The way I expected that function to work is that it will give me a list of products from the app store.
Please correct me and clarify

 

Hi PunteetK,

Sorry you are right - I skipped a step in my instructions. You can RequestAllProductListings to get a list of the IAP options that can be purchased in the app.

Then you want to call WP8Goodies.IAP.GetProductLicense("productID") to get the license for a specific IAP product. You can then check the .IsActive value on this ProductLicense - if it is true, then the player owns that IAP (they have bought it).

Hope this helps,

-Kyle

 

Hi Kyle,

Windows has decided to feature my game on the Windows Phone store but they said I had 2 problems with IAP. I do not know how to resolve these issues using your plugin, and I need to fix it immediately.
Please send me a sample source code of how I will deal with this in the game.


This is the first issue, related to product consumption:

This is the second issue, related to product prices:

I can also provide you with my current implementation for IAP.

It is like this

Code (CSharp):

1. void OnRetrieveProductListingSucceeded (string a_ProductID, WP8Goodies.ProductListing a_ProductListing)
2.     {
3.         switch(a_ProductID)
4.         {
5.         case("@@@@"):
6.             if(PlayerPrefs.GetInt("######", 0) == 0)
7.             {
8.                 PlayerPrefs.SetInt("######", 1);
9.             }
10.             break;
11.         case("*******"):
12.             if(PlayerPrefs.GetInt("######", 2) != 14)
13.             {
14.                 PlayerPrefs.SetInt("######", 14);
15.             }
16.             break;
17.         }
18.         m_ProductListingResponse = "Got listing for " + a_ProductID + " of type " + a_ProductListing.ProductType + " for price " + a_ProductListing.FormattedPrice;
19.     }

 

Hi PuneetK,

For the first issue, I have a new fix that is almost ready for release - if you send me a PM with your Asset Store Invoive No. for the purchase, I can send you the early build. This will fix your first issue, and allow you to properly award the consumable IAP even after exiting the flow part-way through the purchase as described.

The second issue however you should be able to resolve by making use of the value returned by ProductListing.FormattedPrice for each item - it should return a value that you should display for each IAP item inside your application that will match the price shown in their store page, rather than hard-coding the cost values to just show the prices for one region (e.g. US$).

Let me know if you have any issues with this,

-Kyle

 

Sent you a mail.

Also, could you put up some sample code for the second issue?

 

Hi PuneetK,

Here is how you should display the prices in-game, note that you need to do something with the ProductListing details to update your GUI based on how your game works, this part is up to you.

Code (CSharp):

1. void UpdateAllProductListings()
2.     {
3.         WP8Goodies.IAP.OnRetrieveAllProductListingsFailed += HandleOnRetrieveAllProductListingsFailed;
4.         WP8Goodies.IAP.OnRetrieveAllProductListingsSucceeded += HandleOnRetrieveAllProductListingsSucceeded;
5.         WP8Goodies.IAP.RequestAllProductListings();
6.     }
7.  
8.     void HandleOnRetrieveAllProductListingsSucceeded (List<WP8Goodies.ProductListing> a_AllProductListings)
9.     {
10.         WP8Goodies.IAP.OnRetrieveAllProductListingsFailed -= HandleOnRetrieveAllProductListingsFailed;
11.         WP8Goodies.IAP.OnRetrieveAllProductListingsSucceeded -= HandleOnRetrieveAllProductListingsSucceeded;
12.  
13.         //Just retrieved all the product listings - need to go through and update some GUI for my items
14.         for(int i = 0; i < a_AllProductListings.Count; i++)
15.         {
16.             WP8Goodies.ProductListing _ProductListing = a_AllProductListings[i];
17.  
18.             //Use this product listing to update your GUI - create a new button for it, or just change some text fields
19.             string _ProductName = _ProductListing.Name;
20.             string _ProductID = _ProductListing.ProductId;
21.             string _ProductPrice = _ProductListing.FormattedPrice;
22.  
23.             Debug.Log("You should charge a total of [" + _ProductPrice + "] for product [" + _ProductName + "] with ID [" + _ProductID + "].");
24.         }
25.     }
26.  
27.     void HandleOnRetrieveAllProductListingsFailed (string a_ErrorMessage)
28.     {
29.         WP8Goodies.IAP.OnRetrieveAllProductListingsFailed -= HandleOnRetrieveAllProductListingsFailed;
30.         WP8Goodies.IAP.OnRetrieveAllProductListingsSucceeded -= HandleOnRetrieveAllProductListingsSucceeded;
31.  
32.         Debug.LogError("Got an error when trying to retrieve all product listings : " + a_ErrorMessage);
33.     }

 

Will I be able to test this from a build directly run from Unity?

Here's my implementation, the rest of the code is exactly the same as yours. Let me know if it's right.

Code (CSharp):

1. void HandleOnRetrieveAllProductListingsSucceeded (List<WP8Goodies.ProductListing> a_AllProductListings)
2.     {
3.         WP8Goodies.IAP.OnRetrieveAllProductListingsFailed -= HandleOnRetrieveAllProductListingsFailed;
4.         WP8Goodies.IAP.OnRetrieveAllProductListingsSucceeded -= HandleOnRetrieveAllProductListingsSucceeded;
5.        
6.         //Just retrieved all the product listings - need to go through and update some GUI for my items
7.         for(int i = 0; i < a_AllProductListings.Count; i++)
8.         {
9.             WP8Goodies.ProductListing _ProductListing = a_AllProductListings[i];
10.            
11.             //Use this product listing to update your GUI - create a new button for it, or just change some text fields
12.             string _ProductName = _ProductListing.Name;
13.             string _ProductID = _ProductListing.ProductId;
14.             string _ProductPrice = _ProductListing.FormattedPrice;
15.             switch(_ProductID)
16.             {
17.             case("endless"):
18.                 PlayerPrefs.SetString("endlessPriceLocal", _ProductPrice);
19.                 break;
20.             case("huesAllUnlocked"):
21.                 PlayerPrefs.SetString("unlockPriceLocal", _ProductPrice);
22.                 break;
23.             case ("huesbasic"):
24.                 PlayerPrefs.SetString("basicPriceLocal", _ProductPrice);
25.                 break;
26.             case ("huesmedium"):
27.                 PlayerPrefs.SetString("mediumPriceLocal", _ProductPrice);
28.                 break;
29.             case ("huesadvanced"):
30.                 PlayerPrefs.SetString("advancedPriceLocal", _ProductPrice);
31.                 break;
32.             }
33.             Debug.Log("You should charge a total of [" + _ProductPrice + "] for product [" + _ProductName + "] with ID [" + _ProductID + "].");
34.         }
35.     }

And in the GUI Code, I am just pasting the PlayerPrefs value there.

Let me know if this is correct?

 

Hi PuneetK,

That looks good - all you have to do next is when the user navigates to the IAP Purchase screen, you will update the text labels using these player prefs values, e.g:

Code (CSharp):

1. EndlessPurchasePrice.text = PlayerPrefs.GetString("endlessPriceLocal");

 

Yep, that's what I've done!

 

Hi there, just bought the plugin, not sure if this is the right place to get support.

I'm trying to update live tiles, using the following code:

Code (CSharp):

1. string liveTileContent = "Best Score: 100";
2. WP8LiveTileHelper.UpdateFlipTileData("", 0, "Stats", liveTileContent, liveTileContent,
3.     "appdata:/Assets/WP8Tiles/tile_small.jpg",
4.     "appdata:/Assets/WP8Tiles/tile_med.jpg",
5.     "appdata:/Assets/WP8Tiles/tile_large.jpg");

I get the following error when running the game:

An exception of type 'System.UriFormatException' occurred in System.ni.dll and wasn't handled before a managed/native boundary
Exception: Invalid URI: The format of the URI could not be determined.
Type: System.UriFormatException

I have also tried using the standard code that comes with the plugin instead and I get exactly the same error:

Code (CSharp):

1. WP8LiveTileHelper.UpdateFlipTileData("test", 1, "Silly Stats", "Silly Stats", "Silly Stats",
2.     "http://profile.ak.fbcdn.net/hprofile-ak-ash3/s160x160/164146_176567499045827_1075200_a.jpg",

4.     "http://blowfishstudios.com/sites/all/themes/blowfish/logo.png");

If anyone could point me in the right direction that would be great! Thanks!

 

Hi bbeckford,

What version of Unity / Windows Phone are you running it on?

 

Unity 4.5.3 and Windows Phone 8 (not got device with me right now for the actual version number but it's the latest version a UK Lumia 820 can be).

Thanks Kyle!!

 

The actual OS version is 8.0.10517.150.

Also, is "appdata:/Assets/WP8Tiles/tile_small.jpg" the right URL structure for a local image?

Thanks
